[0039] With the improvement of people's living standards, the comfort and safety of the seat are more and more valued by automobile manufacturers. Under such circumstances, zero-gravity seats have emerged. In the zero-gravity sitting position, the human spine has a large inclination angle. When a collision or sudden braking occurs, the occupant is easily squeezed relative to the seat, the spine is compressed, and there is a large safety hazard.

[0040] As Figures 1 to 3 shown, the sliding rail device 100 of the present application is used in a mobile carrier, which includes a sliding rail assembly 1, an adjusting assembly 2, and a collapse structure 3. The sliding rail assembly 1 includes a first sliding rail 11 and a second sliding rail 12, the first sliding rail 11 is used to be mounted to the base of the mobile carrier, the second sliding rail 12 is used to be mounted to the seat of the mobile carrier, and the second sliding rail 12 is formed with a mounting portion 13; the adjusting assembly 2 includes an adjusting portion 21, the adjusting portion 21 is partially mounted to the mounting portion 13, and the adjusting portion 21 can move on the first sliding rail 11 in the front-rear direction, so as to adjust the position of the second sliding rail 12 in the front-rear direction of the first sliding rail 11 under the movement of the adjusting portion 21; the collapse structure 3 is arranged on the second sliding rail 12 and located on one side of the mounting portion 13 in the front-rear direction, and the strength of the collapse structure 3 is less than that of the second sliding rail 12, so that when the first sliding rail 11 is subjected to external force, the adjusting portion 21 moves towards the inside of the collapse structure 3 along with the first sliding rail 11.

[0041] The technical scheme of the present application provides a support basis for the entire sliding rail system by fixing the first sliding rail 11 on the base of the mobile carrier. The second sliding rail 12 is mounted at the bottom of the seat. The adjusting portion 21 is mounted on the mounting portion 13 of the second sliding rail 12 and can move on the first sliding rail 11 in the front-rear direction to adjust the position of the seat. The collapse structure 3 is designed to be weaker than the second sliding rail 12. When a collision occurs, the first sliding rail 11 is subjected to impact force, and the adjusting portion 21 moves towards the inside of the collapse structure 3 along with the first sliding rail 11. Since the collapse structure 3 has low strength, it will deform before other parts, absorb part of the impact force, and play a buffering role. By deforming the collapse structure 3 to absorb the impact energy, the passengers sitting on the seat are protected from injury.

[0042] It can be understood that the stability of the sliding rail movement can be increased by increasing the number of sliding rail assemblies. A plurality of sliding rail assemblies 1 can be arranged in parallel, and each sliding rail assembly 1 can share part of the weight of the seat and the passenger, thereby reducing the burden on a single sliding rail. In addition, the plurality of sliding rail assemblies 1 can provide multiple contact points, making the seat more stable when moving and reducing the possibility of shaking and tilting.

[0043] It can be understood that the adjusting portion 21 can be manually or electrically moved freely on the first sliding rail 11 in the front-rear direction. The precise adjustment of the seat in the front-rear direction is realized, and the individual needs of the passengers are met.

[0044] In an embodiment, the collapse structure 3 is provided at least two, and the at least two collapse structures 3 are arranged on both sides of the mounting portion 13 in the front-rear direction.

[0045] It can be understood that when the vehicle is in collision or other emergency situations, the seat may be subjected to external force impact from different directions. By providing the collapse structure 3 on both sides of the mounting portion 13 in front and rear, the impact energy can be more effectively absorbed and dispersed. No matter the impact comes from the front or the rear, the collapse structure 3 can play a role, reduce the impact force on the second slide rail 12, and protect the safety of the passengers. Different collision situations may produce impact forces of different directions and intensities. By providing the collapse structure 3 on both sides of the mounting portion 13, the slide rail device 100 can be more adaptable to various collision situations. The versatility and reliability of the slide rail device 100 are improved, and it can play a good protection role in different types of vehicles and collision scenes.

[0046] In other embodiments, when a collision occurs, multiple slide rail assemblies 1 are provided, and each collapse structure 3 can independently absorb a part of the impact energy, thereby reducing the impact force on the second slide rail 12. And multiple collapse structures 3 can more evenly disperse the impact force, prevent the seat mounted on the second slide rail 12 from shifting or tilting, and ensure the stability of the seat.

[0047] In an embodiment, the adjustment assembly further comprises a threaded sleeve base 54 and a lead screw 53. The threaded sleeve base 54 is mounted on the side of the first slide rail 11 facing the second slide rail 12; the lead screw 53 is threadedly connected with the threaded sleeve base 54, and can rotate to move forward and backward relative to the threaded sleeve base 54, and the adjustment portion 21 is drivingly connected with the lead screw 53, so that the adjustment portion 21 can adjust the position of the second slide rail 12 in the front-rear direction of the first slide rail 11.

[0048] In this way, the rotation and movement of the lead screw 53 drive the second slide rail 12 to make precise position adjustment on the first slide rail 11. Not only the accuracy and convenience of adjustment are improved, but also the stability and relative stillness between the components during the adjustment process are improved.

[0049] Specifically, the adjusting assembly further comprises a driving motor 51 and a gear box 52, the driving motor 51 is arranged on one side of the slide rail assembly 1, the gear box 52 comprises a worm gear, wherein the worm is in transmission connection with the output end of the driving motor 51, the worm wheel is in transmission connection with a lead screw 53, the adjusting part 21 is in rotational connection with the lead screw 53, and the adjusting part 21 is fixedly connected with the gear box 52, when the lead screw 53 rotates, the adjusting part 21 rotates with the lead screw 53 but no relative displacement is generated, the lead screw 53 can move forward and backward along a threaded sleeve base 54 to move relative to the first slide rail 11 and simultaneously drive the second slide rail 12 to move. The electric adjusting mode realizes the accurate control of the position of the second slide rail 12 through the precise gear and the lead screw 53 mechanism, so that the passenger can conveniently and quickly adjust the seat position according to personal preferences or needs.

[0050] In an embodiment, the mounting part 13 comprises a mounting hole 14, and the adjusting part 21 comprises a compression shaft 22, the compression shaft 22 passes through the mounting hole 14 and is connected with the second slide rail 12.

[0051] It can be understood that when the compression shaft 22 passes through the mounting hole 14 and is connected with the second slide rail 12, it forms a stable connection point, so that the adjusting part 21 can freely move on the first slide rail 11 while maintaining the transmission connection with the second slide rail 12. The movement of the adjusting part 21 is transmitted to the second slide rail 12 through the compression shaft 22, so that the second slide rail 12 moves in the front-rear direction on the first slide rail 11, and the adjustment of the position of the second slide rail 12 is realized. At the same time, the compression shaft 22 is not only used for connecting the adjusting part 21 and the second slide rail 12, but also can trigger the compression of the crush structure 3 when an impact occurs. When an impact or other external force occurs, if the impact force is large enough, the external force will be transmitted to the adjusting part 21 through the first slide rail 11 and then to the compression shaft 22, so that the compression shaft 22 compresses the crush structure 3, and the crush structure 3 can orderly deform or break when compressed by the compression shaft 22 to absorb and disperse the impact energy.

[0052] In an embodiment, the crush structure 3 comprises a crush groove 31, the crush groove 31 is arranged on the second slide rail 12 and located on one side of the front-rear direction of the mounting part 13.

[0053] It can be understood that by arranging the crush groove 31 on the second slide rail 12, the number of the crush groove 31 can be one or more, which is not limited, and the shape of the crush groove 31 can be designed according to needs, such as rectangle, trapezoid, circle, irregular shape or other suitable shape. To adapt to different installation conditions to optimize the energy absorption effect. In addition, the profile and length can be calibrated according to the vehicle collision acceleration and energy.

[0054] In normal circumstances, the collapse groove 31 does not work, and the partial adjusting part 21 is fixedly connected with the second slide rail 12, so that the second slide rail 12 can move along the first slide rail 11. When an impact occurs, the first slide rail 11 is subjected to an external force, and the adjusting part 21 moves with the first slide rail 11 towards the collapse structure 3. Due to the collapse groove 31 on the second slide rail 12, the strength of the second slide rail 12 at the position is reduced, and the adjusting part 21 connected with the second slide rail 12 compresses the second slide rail 12 around the collapse groove 31, and the second slide rail 12 around the collapse groove 31 deforms to absorb the impact energy. In this way, the processing difficulty of the collapse structure 3 is also reduced, and the manufacturing cost is saved.

[0055] In an embodiment, the collapse structure 3 further comprises a convex structure 32, the convex structure 32 comprises a plurality of spaced tooth-shaped elements capable of receiving an external force and deforming, and absorbing energy, and the convex structure 32 is arranged on the groove wall in the upper and lower direction of the collapse groove

[0056] It can be understood that each tooth-shaped element has a specific geometric shape and size, and can elastically or plastically deform controllably when subjected to an external force, thereby effectively absorbing and dispersing the energy carried by the external force. When an impact occurs, the convex structure 32 can first contact and trigger the collapse of the collapse groove 31, and the convex structure 32 is impacted and deformed, which absorbs a part of the impact energy and slows down the impact force on the second slide rail 12. At the same time, it is also helpful to guide and control the direction of the collapse. In addition, the convex structure 32 can be made of metal, plastic or other hard materials, depending on the design requirements, which are not limited here. When the material of the convex structure 32 and the material of the second slide rail 12 are the same, they can be integrally arranged. By integrally forming, the production process can be simplified and the overall strength of the connection can be improved.

[0057] In an embodiment, the collapse structure 3 further comprises a soft metal, and the soft metal is filled in the collapse groove 31.

[0058] It can be understood that the soft metal can deform greatly when subjected to an external force due to its low hardness and high ductility, thereby absorbing and dispersing the impact energy. When subjected to an external impact, the part of the soft metal contacting the adjusting part 21 will first deform, thereby slowing down the impact on the second slide rail 12.

[0059] In an embodiment, the convex structure 32 is provided with at least two convex structures 32, and the at least two convex structures 32 are arranged on both sides in the upper and lower direction of the second slide rail 12.

[0060] It can be understood that by arranging the convex structure 32 on both sides of the second slide rail 12 in the upper and lower directions, it can be ensured that when an impact occurs, the impact force can be more evenly dispersed and absorbed in the upper and lower directions.

[0061] In an embodiment, the slide rail device 100 further comprises a locking assembly 4. The locking assembly 4 comprises a base 42 and a locking part 41, the base 42 is connected with the second slide rail 12, the locking part 41 is movable in a direction close to or away from the adjusting part 21, the locking part 41 has an unlocking position and a locking position in its movable stroke; wherein, when the locking part 41 is in the locking position, the adjusting part 21 is connected with the base 42, so that the adjusting part 21 can drive the second slide rail 12 to move and the two are relatively static; when the locking part 41 is in the unlocking position, the adjusting part 21 is disconnected with the base 42, so that the adjusting part 21 can move relatively with the second slide rail 12.

[0062] It can be understood that when the locking part 41 is in the locking position, it effectively connects the adjusting part 21 and the base 42. Such connection not only enables the adjusting part 21 to drive the second slide rail 12 to move (also enables the two to be relatively static during the movement, so that the connection between the adjusting part 21 and the second slide rail 12 is firm and will not be easily disconnected by external force. When it is needed to separate the adjusting part 21 and the second slide rail 12, the locking part 41 is moved to the unlocking position. In this position, the locking part 41 no longer provides a connection, so the adjusting part 21 and the second slide rail 12 can move relatively. Part of the adjusting part 21 can compress the crush structure 3 to absorb and disperse impact energy.

[0063] In an embodiment, the locking assembly 4 further comprises an initiator, a blasting cavity is formed in the base 42, and the initiator is installed to the blasting cavity, which is used to generate high-pressure gas to push the locking part, so that the locking part moves from the locking position to the unlocking position.

[0064] It can be understood that the initiator can include but is not limited to an electrical initiator, a wireless remote control initiator, and a chemical initiator. The initiator can provide conditions for the activation of the crush structure 3. The initiator can generate a large amount of gas instantaneously to occupy the blasting cavity, so that the air pressure in the blasting cavity increases sharply, generating a large enough pressure to push the locking part 41 from the locking position to the unlocking position, rapidly changing the position of the locking part 41 to unlock the connection between the adjusting part 21 and the second slide rail 12 in a very short time, enabling the adjusting part 21 and the second slide rail 12 to move relatively, and enabling the adjusting part 21 to compress the crush structure 3 to absorb impact energy.

[0065] In an embodiment, the locking assembly 4 further comprises a sensor and a control system, the sensor is used to be installed to the moving vehicle, and the control system is electrically connected with the sensor and the initiator.

[0066] It can be understood that when the mobile carrier collides, the collision signal can be transmitted to the mobile carrier through the sensor in the mobile carrier, and after logical operation, when the acceleration exceeds the set threshold, the detonator is sent a point explosion instruction signal, so that the lock part 41 is pushed by the detonator. In this way, the reaction speed and safety of the locking assembly 4 are improved.

[0067] In an embodiment, the adjusting part 21 is formed with a locking groove 15, the base 42 is formed with a locking hole 16 corresponding to the locking groove 15, the locking hole 16 and the locking groove 15 form a sliding channel in communication, and the locking part 41 is movably arranged in the sliding channel. The locking part 41 is in the sliding channel to form a locking position, and the locking part 41 is in the locking hole 16 to form an unlocking position.

[0068] It can be understood that in the absence of collision, the locking part 41 is located in the sliding channel and is in the locking position, preventing relative movement between the adjusting part 21 and the second slide rail 12. When the collision occurs, the detonator in the locking assembly 4 is activated to generate enough force to push the locking part 41. The locking part 41 moves from the locking position to the unlocking position, i.e. away from the locking groove 15 into the locking hole 16, so that the adjusting part 21 can move relative to the second slide rail 12, so that the adjusting part 21 can slide along the second slide rail 12 or compress the crush structure 3 to absorb the collision energy. In this way, by simply moving the locking part 41, the locking position can be quickly switched to the unlocking position, improving the ease of use and reliability of the device.

[0069] In addition, it is worth mentioning that the base 42 can be connected with any part of the second slide rail 12, and the working of the crush structure 3 is mainly not particularly limited. When the base 42 is arranged on the outer surface of the second slide rail 12, the second slide rail 12 is further formed with a through hole in communication between the locking groove 15 and the locking hole 16. In this way, the locking strength between the second slide rail 12 and the adjusting part 21 is further enhanced.

[0070] The present application also provides a mobile carrier, which comprises the slide rail device 100, and the specific structure of the slide rail device 100 is referred to the above-mentioned embodiments. Since the mobile carrier adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. It can be understood that the mobile carrier includes but is not limited to vehicles, trains, airplanes, and ships.
